Thematic Map

A Thematic map is very easy to read and understand and they are the most common type of map. This is a Thematic map that shows a July prediction for the November 2008 election. The blue shows the Democrat states, the red shows the Republican states and the yellow show the states that are predicted to be a toss-up.
